Hm, does 2.5 exist in the wild yet?  I checked Fedora rawhide, which
is my usual go-to platform for bleeding-edge stuff, but they are still
at 2.4.58.

As for the patch itself, I'm wondering about

+      LDAP_LIBS_FE="${ac_lib:+-l}$ac_lib $EXTRA_LDAP_LIBS"

That seems undesirably intimate with the implementation details
of AC_SEARCH_LIBS.  Surely there's a better way?
